When the fuel vaporizer is in position in the fuel intake pipe, it obstructs the straight passage of fuel and causes the same to travel with a whirling motion outwardly toward the inner walls of the fuel pipe which are warm and cause the fuel to vaporize to a great extent. The baffle plates being serrated present ridges to the inflowing fuel, and any drops of fuel are broken and vaporized.

As shown in the drawings, the machine may comprise a base support 20 and a base member 21 having a depression 22 to receive the lower die members. The lower die members include a base or stationary plate 23 having its upper face 24 lying in a horizontal plane, and an offsetting plate 25 having its upper face 26 lying in an oblique plane. Immediately adjacent the. offsetting plate 25 is a pair of forming plates 27 and 28 having their upper faces inclined so that all of the several plates 23, 25, 27 and 28 are in stepped relation to each other. To secure the several members in position, a plate 29 is provided and adapted to be engaged by screws 303O operating in the base member 21.

A movable die member co-operates with the stationary die, and comprises a reciprocating member 32 carrying a holder 33 having an opening 34 to receive a reciprocating plate 35, having its lower operating face 36 lying in a horizontal plane and in alignment with plate 23. Adjacent the plate is an offsetting blade 37 having an oblique operating face, and also within theopening 34 are forming plates 38 and 39 having oblique operating faces. To retain the several plates in place, I provide the plate 40 engaged by screws 4141 operating in the holder 33.

Operating in a depression 45 and between plates'4646 and the base 21 is a longitu dinally movable member 47 provided with a stem 48 pivoted at 49 to a portion of the movable member 47. As best shown in Figs. 1 and 4, stem 48 carries a stationary jaw 50 co-operating with a movable jaw 51 closed by means of a screw 52 and separated by a spring 53. Portions 54 and 54 are adapted to hold and firmly embrace a blank to be presented to the die members for the forming operation. To automatically feed the longitudinally movablemember toward the dies, the member 47 may be provided with lugs 55 against which a compression spring 56 operates.

To serrate and form spirally a blank 13 or 14, the stem 48 may be swung upwardly on the pivot 49 and the jaws adjusted to receive the blank. The stem is then returned to its position within the guide 57 and moved toward the die members until, as shown in Figs. 4 and 5, the front end of the blank engages the plate 27. The blank is yieldingly held away from the base plate 23 by means of a spring pressed plunger 59, operated by spring 60 within a recess 61 closed by the screw 62. Upon downward reciprocation of the member 32, face 36 of plate 35 engages the blank and brings it into engagement with face 24 of plate 23. At the same time, offsetting plates 25 and 37, co-operating with each other and with plates 23 and 35, offset a portion of the blank equal to the width of the blades 25 and 37. Upon upward movement of the member 32, plunger 59 pushes the blank upwardly so that the step formed in it is brought out of engagement with the plates 23 and 25. The spring pressed longitudinal member 47 is then moved forwardly to bring the step just formed into engagement with blade 27 so that another flat surface is presented to the offsetting blades. Upon further downward reciprocation of the member 32, a portion of the blank is again offset, and the portion already offset is held between blades 27 and 38 to prevent it from springing from the desired form.

Again, upon the upward stroke of member 32, the blank is moved upwardly by plunger 59 and the steps formed in the blank are moved forwardly to engage plates 27 and 28, and upon downward movement of member 32, the flat part of the blank is offset and the portions already offset are held between the forming plates 27 and 38 and forming plates 28 and 39. The pairs of forming plates 27-38 and 2839 may be proportioned and inclined so that they will assist the first pair of plates 25-37 by shearing a portion of each step, generally the inner portions thereof removed slightly from the outer ends of the blank, which outer ends are sheared by the first plates 2537.

As will be best understood by reference to the accompanying drawings, the offsetting blade 25 and forming blades 27 and 28 incline downwardly from one side of a central longitudinal axis of the blank acted upon and incline upwardly from the other side of that axis, and that the offsetting blade 37 and forming blades 38 and 39 co-operate to form the blank spirally as well as to serrate it as the blank. is successively stamped and fed. The member then formed passes through the opening formed by the cutaway portion 65 of base 21 and cutaway portion'66 of holder 33. When the blank has been subjected to the stamping and forming operation to the desired extent, the machine may be stopped and the finished baffle plate removed.

The dies described may be used with punch presses of ordinary construction, or may form part of automatic mechanisms for stamping and feeding the blanks.

Having thus described my invention, what I claim is new and desire to secure by Letters Patent of the United States is:

1. The method of making a serrated baffle plate from a flat metal blank which comprises stamping the lateral edges of the blank in successive steps to form successive offsets, and twisting the blank spirally during said stamping operation.

2. The method of making a baffle member of the class described which comprises subjecting the blank to a pair of shearing dies disposed obliquely to the plane of said blank, said dies cutting steps in the opposite edges of said blank, said steps being offset in opposite directions.

3. The method of making a bafile member of the class described which comprises subjecting the blank to a pair of shearing dies disposed obliquely to the plane of said blank,

said dies cutting offsets in the opposite edges of said blank, the offsets at opposite edges extending in opposite directions from the plane of the original blank.

41-. The method of making baffle members of the class described which comprises subjecting the blank to a first pair of dies disposed obliquely to the plane of said blank and transversely thereof, said first pair of dies cutting offsets in the opposite edges of said blank, the offsets along one edge of said blank projecting in an opposite direction to the offsets along the other edge of said blank, and subjecting said blank to the action of the second pair of dies co-operating with said first pair of dies to twist the blank.

5. Means for making baflie plates of the class described, comprising a base, a reciproeating member co-operating therewith, means for feeding a blank relative to said base and said reciprocating member, and

a pair of ofl'setting dies carried by said base and said reciprocating member, each of said dies comprising an intermediate portion which moves only tothe plane of the blank and an end portion moving past the plane of said blank, whereby the opposite edges of said blank are offset in opposite directions.

6. Apparatus of the class described com prising a base, a reciprocating member cooperating therewith, an offsetting die supported on said base, an offsetting die carried by said reciprocating member, means for automatically advancing successive portions of the blank between said dies, said dies extending transversely of the path of movement ofsaid blank and being inclined with, respect to the plane of said blank, the end portion of one die extending above the plane of said blank and the end portion of the other die extending below the plane of said blank whereby the opposite edges of said blank are offset in opposite directions, and means for moving said blank in the plane of the die operation for co-operating with said feeding means.

In witness whereof, I hereunto subscribe my name this 29th day of April, 1922.

JOSEPH lVROBLEVVSKI.
